Earlier, that calm was interrupted about 8:20 p.m. Central time when a woman walked West Florissant Avenue waving a sign that read, “I support Darren Wilson” and shouting, “Y’all need to get your facts straight.”

Washington Post reporter DeNeen Brown said someone hit the woman over the head and another grabbed the sign. Police rushed to the scene. And officers put her in a police vehicle and drove away.

“That sign was meant to provoke us. I asked the police why are you letting her protest causing problems over here?” said Tenisha Wheeler, 30, who lives in St. Louis City. She added, “I wouldn’t dare go to a rally supporting Wilson with my own self.”

Amber Howland, 30, who traveled from Alton, Ill., also saw the incident.

“The police walked her past,” she said. “I said I’m white I can get through the crowd. I was going to hit this b—-. They pushed me away. And ran and put her in a truck.”

As the rain grew thicker Wednesday night, many protesters hid under a tent before joining the crowd again.
